. FUEL SAVER.

Application filed December 3, 1920.

Be it known that I, RANK FRANCIS, a subject of the King of Great Britain, of the city of Winnipeg, in the Province of Manitoba, Canada, have invented certain new and useful Improvements in Fuel Savers, of which the following is the specification.

The invention relates to improvements in fuel savers and the primary object of the invention is to provide a device which can be inserted in a smoke pipe and which will effect the burning of the otherwise unconsumed gases which customarily escape out the chimney and by so doing effect a considerable saving of fuel.

A further object of the invention is to construct the appliance in a simple, incapensivc and durable manner and so that it can be readily inserted in the smoke pipe and also so that it can be regulated as occasion demands.

IVith the above more important objects in view tl e invention consists essentially in the arrangement and construction of parts hereinafter more particularly described and later pointed out in the appended claim, reterence being had to the accompanying drawing in which Fig. 1 is a side view of a furnace and smoke pipe showing my invention installed in the smoke pipe.

Fig. 2 is an enlarged detailed longitudinal vertical sectional view centrally through the device as it appears in the smoke pipe.

Fig. 3 is an enlarged detailed horizontal sectional view centrally through the device as it appears in the smoke pipe.

Fig. 4 is a cross sectional view through the smoke pipe and the appliance, the section being taken at 4+4 Fi 2.

In the drawing like characters of reference indicate corresponding parts in the several figures.

1 represents a furnace of ordinary design and 2 the smoke pipe leading from the furnace and communicating with a chimney in the ordinary way. In a location at a suitable distance from the furnace and in the smoke pipe I locate my appliance which as a matter of convenience is formed as a pipe unit which can be inserted in the smoke pipe at the place desired.

In constructing my appliance I utilize a length of furnace pipe 3 of standard size and which will telescope with the ordinary furnace or smoke pipes used. At one end Serial No. 428,142.

of the pipe 3 I locate a let circular damper at mounted on the damper rod 5 which is provided outside the pipe with a finger piece in the form of an eye 6. The damper is supplied with escape openings at.

At the other end of the pipe 3 I locate a cross rod 7 on which I mount a pair of opposing discs 8 and 9 having inwardly flanged edges and formed with suitably positioned openings 10 and 11.

In a location between the damper and the disc 8 I locate an elbow 12 having one end permanently secured in any suitable man ner to the pipe 3 and the other end extend ing towards the rod 7 and positioned concentric to the longitudinal axis of the pipe This elbow isopen to exterior air and isprovided with an air regulator 13 in the form of a flat disc fitted with a handle 15 and provided with spring arms 16, the arms being adapted to enter and contact with the inner side of the elbow and by so doing hold the regulator in any adjusted position.

I may here state that I prefer the disc 14 to be flat so that when the regulator is closed against the pipe there is always an air inlet opening provided, such being due to the fact that the pipe 3 curves away from the disc at the sides.

17 is a guard plate spaced from the inner end of the elbow, the guard being supported by the elbow by substantially U-shaped bracket arms 18 and 19. The guard is circular and has a diameter preferably slightly 7ljarger than the internal diameter of the el- 20 and 21 are a pair of spaced bafiie plates crossing the elbow and extending inwardly from opposite sides thereof.

When this appliance is in use the damper a is regulated in the customary way and the regulator is withdrawn or closed in as experience teaches.

The discs 8 and 9 serve to break up the eddycurrents and the elbow forms a heating and circulating chamber contained within the pipe 3, air being supplied to this charm her through the opening at the regulator. Obviously oxygen is admitted with the air and this mixes with the gases in the pipe and the resultant mixture passes back to the fire box of the furnace where it is consumed.

I have found by actual experience that this device operates very satisfactorily and it takes but little practice to determine just how the regulator 13 and the value 4 should be set to obtain best results under existing conditions.

vWhat I claim as my invention is:

A fuel saver comprising a smoke pipe, an adjustable damper located in one end of the pipe, a supporting rod centrally crossing the other end of the pipe, a plurality of spaced discs mounted on the rod and positioned at right angles thereto, an elbow contained within the pipe between the damper and the discs and having one end axially aligned With the longitudinal axis of the pipe and the other end extending laterally and openvbow and a disc like guard plate spaced from and opposing the inner end of the elbow and carried thereby.

Signed at Winnipeg, this 18th day of No- 20 veinber 1920.

FRANK FRANCIS.
